CARY N. HOPKINS, OF PASADENA, AND RICHARD T. FRANK, 0F LOS ANGELES, CALIFORNIA.

CARTON.

To all whom it may concern:

Be it known that we, CARY N. HOPKINS, a citizen of the United States, residing at Pasadena, and RICHARD T. FRANK, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented a new and useful Carton, of which the following is a specification.

One object of the present invention is to provide a carton which is sealed so as to prevent access to the contents thereof without breaking the carton. Such a carton is desirable in many cases to prevent substitution of other articlesfor those originally contained in the carton.

Another object of this invention is to provide a carton with end seals which when at the bottom of the carton securely fasten or lock the same and makes it practically impossible for i he contents to fall out when the same is picked up or handled, obviating breaking and damage to the contents.

Other objects of the invention will apprar hereinafter.

The accompanying drawings illustrate an embodiment of the invention, and referring thereto:

Figure 1 is a plan of a blank suitable for forming the carton according to our invention. Figs. 2, 8 and 4 are perspective views, showing successive positions in the formation of the carton. Fig. 5 is a broken perspective view, showing the final operation in the folding of the blank'to form the carton. Fig. 6 is a sectional view of the end portion of the completed carton with the contents for filling therein. Fig. 7 is a transverse section of the carton in completed condition.

The carton is formed of a blank of paper,

cardboard or other suitable material, bent or creased along the lines indicated at dotted lines in Fig. 1 to form four side members 1, 2, 3, 4, and a side flap 5. End flaps 6, 7 8 and 9 are formed on the side members 1 to 4 in any suitable order so as to be adapted to fold on one another to form the ends of the carton as hereinafter set forth. Said flaps may be similarly formed at opposite ends of the box, as shown in Fig. 1, or may be variantly arranged. One of the end flaps indicated at 9, is made longer than the other end flaps so as to provide a supplementary flap 1O folded on the flap 9 along the dotted line indicated at 11. The flaps 8 are suffi- Specification of Letters Patent.

ciently short to be received under the folded flap 9 and the flaps 6, 7 and 8 are tapered so as to facilitate the folding thereof into position as hereinafter set forth. Nicks indicated at 12 are preferably formed in the side member 4 by pressing in the paper or pasteboard with a suitable instrument, so as to form projections on theinside of the carton.

The blank may be folded to form the carton as follows: The end flaps 8 on side member 3 herein termed the first side member, are bent up as shown in Fig. 2. Side member 4 herein termed the second side member is bent up as shown in Fig. 2, so as to extend upwardly from one edge of side member 3 and its end flaps 9 are bent at right angles as shown in Fig. 2, so as to extend alongside of the aforesaid flaps 8 on first side member. The supplementary flaps 10 on the end flaps 9 of the secondsidemember 4 are then bent back on the respective end flaps 9 to form U-shaped bends embracing the respective end flaps 8 as shown in Fig. 3.- The side member 2 is then folded up as shown in Fig. 4, so as to extend upwardly from the side member 3 on the opposite side from the side member 4 and its end flaps 7 are bent at right angles so as to extend alongside of and within the end flaps on the aforesaid side members, said flaps 7 being of sufficient length to extend to the opposite side member4 and to be engaged by the projections or. nicks 12 on the side member 4, so as to hold the flaps in position. The carton is now ready to receive the contents or filling, which should be inserted in such manner as to fit more or less tightly against the end flaps 7 holding the end flap s 7 and 8 and the supplementary flap 10 in position. The fourth side member 1 is then turned over and its end flaps 6 tucked into the space between the end flaps 8 and 9 or 10. The side flap 5 is then tucked under the side member 1 and fastened thereto by glue, paste or cement indicated at 14 in Fig. 7. With the carton constructed in this manner, the member 1 being held in position by the cement fastening, prevents withdrawal of any of the end flaps, since the end flap 9 is interlocked by its supplementary flap 10 with the end flap 6 on the The paper or cardboard of which the carton is made is sufiiciently flexible to be folded as above described, but stiff enough to prevent it from being pulled out at the seal withoutbreaking the paper.

The carton above described can be manufactured at the same cost as the ordinary cartons heretofore in use, as in manufacturing no greater amount of material is used, the extra flaps being taken from what has heretofore been waste material.

What We claim is:

1. A carton consisting of a sheet of foldable material, bent to form four side members and provided with end flaps on one of said side members bent to form the ends of the carton, one of said end flaps being longer than the others and being folded back against itself inclosing the flaps on two other of said side members, one of said side members having end flaps extending across the carton and engaging with the opposite side member, and with the first named end flaps to hold them in position to form a sealed end. a

2. A carton consisting of a sheet of material folded to form side members comprising a first side member having an upturned flap at each end, a second slde member extending upwardly from one edge of the first side member and having a side flap at its upper edge, end flaps extending respectively site second side member, said third side member having inward projections engaging with said end flaps on said second side member, and a fourth side member bent from the upper edge of the third side member and overlapping the side flap on said second side member, and having end flaps folded down and tucked within the U-shaped bend of the end flaps on the second side member.

aforesaid end flaps and engaging the oppo- In testimony whereof, We have hereunto set our hands at Los Angeles, California, this 13th day of February, 1913.
